SAMUEL W. FISH, OF PLAINFIELD, NEW JERSEY, ASSIGNOR TO TAYLOR IRON & STEEL COMPANY, OF HIGH BRIDGE, NEW JERSEY, A CORPORATION OF NEW JERSEY.

sarn on VAULT noon.

To all'wltom 'it may concern:

Be it known that I, SAMUEL IV. FISH, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented certaln new and useful Improvements in Safe or Vault Doors, of which the following is a specification.

The present improvement relates to safe or vault doors, the object thereof being to provide an improved double or compound door so constructed that the major part thereof is made as a single casting, but which will have the effectiveness of a pair of doors rigidly secured together, and is in part an improvement upon that shown and described in my contemporaneously pending application, Serial No. 527,129, filed Nov. 10, 1909.

In the present improvement the door is made up of a main door and an inner door located entirely within the main door and secured within such main door by rotating the inner door within the main door.

In the drawings accompanying and forming a part of this specification, Figure 1 is a rear view of this improved door; Fig. 2 is a cross-sectional View thereof, taken in line 2-2, Fig. 1; Figs: 3 and 1 are edge and face views respectively of the inner door; Fig. 5 is a rear view of a somewhat different form of door; Fig. 6 is a crosssectional view thereof, taken in line 6-6, Fig. 5; Fig. 7 is a rear view of a still different form of door; Fig. 8 is a cross-sectional view thereof, taken in line 88, Fig. 7; Fig. 9 is a rear view of a still different form of door; Fig. 10 is a cross-sectional view thereof, taken in line 1010, Fig. 9; Fig. 11 is a rear view of a modified form of door; and Fig. 12 is a cross-sectional view thereof, taken in line 1212, Fig. 11.

Similar characters of reference indicate corresponding parts throughout the figures of the drawings.

In all of these doors it will be observed that the main door comprises a body 2 having a rearwardly extending integral flange 3 of tapered form and provided with looking lugs 4, shown in the present instance as comprising two sets, 5 and 6, the locking lugs of one set alternately disposed with those of the other, whereby a uniform holding of the door in its jamb throughout the Specification of Letters Patent.

Application filed November 10, 1909.

Serial No. 527,127.

entire circumference of the door is obtained, the lugs of one set, as the rear set, backing up the spaces between the lugs of the front set. It will also be observed that in all of these forms of doors the flange is provided with suitable bolt openings 7 for the reception of bolts which may be used for the purpose of preventing the door from being rotated in its seat after it is locked in position by the lugs. Furthermore, in all these forms of doors the rearwardly extending flange is provided on the interior thereof with a door seat 8 for the reception of the inner door, which latter thus partitions the main door into a pair of chambers 9 and 10 separated one from the other within the main door. By reason of this organization, should a burglar be successful in separating the body of the door from the remainder thereof ingress to the safe would still be prevented by reason of the inner door. It will also be observed that in all these forms of doors the inner or chamber-forming door is secured in position by a rotary movement thereof with relation to the main door.

In the form shown in Figs. 1 to l the main door flange is provided with an inwardly extending annular projection or ring 12 against which the inner door is adapted to rest. The flange of the main door is also provided with a series of projections or lugs 13, the inner door being provided with a series of recesses 14 around its periphery for the reception of such lugs, whereby the inner door may be pushed into position when the recesses are in alinement with the lugs and then rotated so as to carry the recesses away from the inner ends of the lugs, whereby it is rigidly secured in position against displacement. Various means could be provided if necessary, to prevent the rotation of the inner door, such as keys, but as the inner door is adapted to fit tightly within the outer door it would be extremely difficult to rotate the door after it is once placed in position.

In the form shown in Figs. 5 and 6 the inner door 20 is of step formation and is secured in position in a substantially similar manner to that shown in Figs. 1 to 4.

In the form shown in Figs. 7 and 8 the inner door 30 is provided with a series of locking lugs adapted to project into the forward chamber 9, and for this purpose the flange of the main door is provided with an annular ring 31 having recesses 32 therein for the passage of the lugs, the body of the inner door 33 engaging the inner face or side of this annular ring 31.

In the form shown in Figs. 11 and 12 the inner door is of tapered formation, tapering in a direction opposite to that of the flange of the main door 40, and is provided with a chamber 41 therein and with locking lugs 42 adapted to co-act with similarly foimed lugs 13 on the interior of the flange of the main door, this inner door etO having an annular shoulder or step 15 around the same cooperating with a similarly formed shoulder or step 46 on the interior wall of the flange of the main door.

In the form shown in F 9 and 10 the inner door 50 is provided with threads 51 adapted to engage similarly formed threads 52 formed on the annular ring 53 projecting inwardly from the main door flange. This door 50 is so formed that that part thereof having the largest diameter, as 55, will fit within a recess 56 of 'the annular seat-forming member for this inner door.

From the foregoing it will be observed that by means of this inner door the main door is separated and divided into a pair of compartments or chambers, and that, although access might be obtained to the first chamber by the separation of the body of the main door from the rest of the door, nevertheless the body of the safe would be still tightly closed against ingress thereto by the inner door, so that all the work of the burglar would have to be repeated in order to get into the safe.

I claim as my invention:

1. A safe or vault door comprising an outer door and an inner door located wholly within and in the rear of the body of the outer door and rigidly secured thereto by cooperating interlocking means on the rotary movement of one of the doors.
